Question

if one angle of a triangle is 75º and the other angles are in the ratio 2 : 3, then the other two angles are
​

Answer 1

Answer:

Given

One ange = 75°

Let second angle = 2x

Third angle = 3x

Property of triangle

Sum of all the angles = 180°

75 + 2x +3x = 180

5x = 180 -75

5x = 105

x = 105/ 5

x = 21

Hence second angle = 2x = 42°

Third angle = 3x = 63°

Answer 2

Answer:

42° and 63°

Step-by-step explanation:

sum of two angle=180°-75°=105°

if x is present in ratio

2x+3x=105°

5x=105°

x= 21°

2x=2×21=42°

3x=3×21=63°
